Application filed August 5, 1922. Serial No. 579,813.

To all whom it may concern.

Be it known that L ADAM MAJnwsKI, a citizen of Poland residing atBuffalo, in the county of Erie and State of New Yorlg have inventedcertain new and useful Improvements in Windows, ofwhich the following isa specification.

This invention relates generally "{to windows for houses, apartments orother build ings, the invention having particular reference to a windowhaving a combination sash which can be moved vertically or swunginwardly, as desired, to open the window.

The invention has for an object to provide a novel and improved windowof the above type, other specific features of the invention relating tothe locking of the window in partially open position.

For further comprehension of the invention and of the objects andadvantages thereof, reference will be had to the following descriptionand accompanying drawings, and to the appended claims in which thevarious novel features of the invention are more particularly set forth.

Fig. 1 of the drawings is a perspective view showing the generalarrangement of my improved window.

Fig. 2 is a face view of the window.

Fig. 8 is an enlarged fragmentary face view showing one of the sidemembers of the type of window shown in Fig. 2.

Fig. 1 is a horizontal sectional view taken on the line i4 of Fig. 3. V

In the drawings I have indicated an ordinary window frame at 10 whichsupports for vertical sliding movement an upper sash 11 and a lower sash12 which are guided in the usual manner and may be locked to gether byan ordinary catch15.

In carrying out my invention the glass panes, indicated. at 13 and 1 1-,are fixed in supplementary sashes or frames 16 and 17, which are ofslightly smaller size than the respective sashes 11 and 12 and arefitted thereinto. These supplementary sashes are hinged at one side tothe main sashes 11, 12 by hinges 19 and are provided with ordinarylocking bolts 20 to lock them in closed position.

With this construction substantially the full window area may beutilized for ventilation if desired, by swinging open the supplementarysashes, while the main sashes may be raised and lowered in the usualextends along one side of the window frame passing through a suitableboring in the sash 12, this rod having formed therein a substantiallylongitudinal slot 26 having a slight helical inclination, the length ofthe slot 26 corresponding approximately to the distance the lower sashis to be raised.

Pivotally connected at one end as at 27 to one of the hinges 19 is alink 28 having a lateral offset or hook 29 on its opposite end which isadapted to engage in the slot 26, being normally urged thereinto by aspring 30 located in the recess 31 in the side member of the sash 12. inwhich recess the link 28 is accommodated. Threaded through the said sidemember is a screw 32 having a knuckled head 33 for adjusting purposes.

By reason of the oblique or helical inclination of the slot 26 thehinged sash 17 will be caused to swing on its hinges 19 in an openingdirection as the main sash 12 is raised while the upward movement of thesash 12 is limited by the engagement of the hook 29 with the 'top ofsaidslot, limiting also the opening movement of the sash 17. If it isdesired to completely raise the sash 12 the screw 32 is turned to liftthe hook 29 out of the slot 26, permitting the sash 12 to be raised orlowered as desired. While the head 33 of this screw 32 is diiiicult ofaccess from the exterior I may in place of this head form a socket inthe end of the screw, necessitating the use of a key to turn the same.

Having thus described my invention what I claim as new and desire toprotect by Letters Patent of the United States is as follows: i

1. In a window, a vertically slidable sash a supplementary pane carryingsash hinged thereto, and means whereby said hinged sash is caused toopen upon vertical movement of said first sash.

2. In a window, a vertically slidable sash, a supplementary panecarrying sash hinged thereto, and a common locking means for lockingeach of said sashes when in partially open position against furtheropening movement.

3. In a window, a vertical element having a heli'cally inclinedlongitudinal slOtthere in, a vertically slidable sash, a supplementarypane carrying sash hinged thereto, and;

a member carried by said hinged sashand normally engaging said slot tocause said hinged sash to swing as the first sash moves vertically.

4. In a window, a vertical element having a helically inclinedlongitudinal slot therein, a vertically slidable sash, a supplementarypane carrying sash hinged thereto, and a member carried by said hingedsash and normally engaging said slot to cause said hinged sash to swingas the first saslr 'inoves vertically, and means for disengaging saidmember from said slot. v

5, In awindow, a vertically slidable sash, a vertical fixed rod at theside of the window and passing through the side eleinent of said sashand formed with a helically inclined longitudinal slot; a supplementary;pane carrying sash hinged to the first sash, and a'link hinged at oneend to the second sash and having a hooked oifset on its other endengaging in the said slot.

, G. In a window, a vertically slidable sash, a vertical fixed rod atthe side of the window and passing through the side element of saidsash-and formed with a helically inclined longitudinal. slot," asupplementary pane carrying sash hinged to the first sash, and

a link hinged at one end to the second sash andhavinga hooked offset onits other end enga ing in the said slot, and a screw threaded into thefirst sash and adapted to bear against said link to lift said ofi's'etfrom said slot.

In testimony whereof I have affixedmy signature.
